What page were you on when that issue was triggered?

If you went to the manual selection page and had a lot of threads, you are likely hitting the PHP max_input_vars setting. This is something that would need to be increased before XF runs (because it happens at PHP start up). Your host should be able to give you guidance as to how to increase a php.ini configuration setting on your server (it varies by configuration).
